Reflected-image videoendoscopic surgical trainer and method of training
First Claim
1. A videoendoscopic surgery trainer for the practice of videoendoscopic surgery techniques on an anatomical structure, the trainer comprising:
- a base having first and second opposing sides, said base being arranged to receive an anatomical structure;
a first wall projecting from the first side of said base;
a second wall projecting from the second side of said base, said second wall having a finite height such that a direct line-of-sight view of the received anatomical object from the second side of the base is blocked, said first wall, second wall and base defining a cavity in which the received anatomical structure is disposed; and
a first mirror attached to said first wall within the cavity, a reflective surface of said first mirror being oriented facing toward said second wall, for reflecting past said second wall a first two-dimensional image of the received anatomical structure.

Abstract
A videoendoscopic surgery training system (10) provides training in videoendoscopic surgery techniques. A base (14) supports a simulated anatomical structure (12). A shield (20) blocks a trainee'"'"'s direct line-of-sight view of the simulated anatomical structure. A reflector assembly (24, 34) reflects an image of the simulated anatomical structure past the shield. A first mirror (24) reflects an image of the simulated anatomical structure that is oriented away from the trainee. A second mirror (34) optically communicates with the first mirror to reflect an image of the simulated anatomical structure that is oriented toward the trainee.

13. A videoendoscopic surgery trainer for the practice of videoendoscopic surgery techniques on an anatomical structure, the trainer comprising:
-
a base having first and second opposing sides, said base being arranged to receive an anatomical structure; a first wall projecting from the first side of said base, said first wall being hingedly attached to said base; a second wall projecting from the second side of said base, said second wall being hingedIy attached to said base, said second wall having a finite height such that a direct line-of-sight view of the received anatomical structure is blocked; a first mirror attached to said first wall, a reflective surface of said first mirror being oriented facing toward said second wall, for reflecting past said second wall a first two-dimensional image of the received anatomical structure viewed from the first side of said base; and a second mirror attached to said second wall, a reflective surface of said second mirror being oriented facing toward said first wall, said second mirror being in optical communication with said first mirror for cooperatively reflecting past said second wall a second two-dimensional image of the received anatomical structure viewed from the second side of said base, wherein at least one of said first and second mirrors is disposed between the first and second walls to reflect the received anatomic structure. - View Dependent Claims (14, 15)

16. A method for training a trainee in videoendoscopic surgery techniques on an anatomical structure, the method comprising the steps of:
-
placing an anatomical structure on a base; blocking a direct line-of-sight view of the anatomical structure with a shield; performing a surgical procedure on the anatomical structure; and reflecting past the shield a reflected two-dimensional image of the anatomical structure corresponding to an at least partially lateral view of the anatomical structure. - View Dependent Claims (17, 18, 19)
